The issue is pretty simple. As Horde, we have to wait about 20-50 minutes for a battleground queue depending on the time of day. On the other hand, alliance get instant queues.
This is happening even though we have cross realm Battleground queueing in TBC Classic.
Would it be possible to consider the possibility of introducing mercenary mode in TBC Classic? It would give horde players the opportunity to enjoy queueing for battlegrounds.
We all know the #nochanges discussion. But I am still proposing it as an idea because the BG queue times are absolutely unbearable.
Edit: We should also take into consideration that when you wait 50 minutes in queue and finally join a BG, there is a high probability for horde players to drop against a premade alliance team in BG, and lose 5 minutes in or less even, and end up having to wait another 50 minutes in queue for the next BG. This happens all the time by the way.
